We have numbers generated for patch cables but I usually label thing like this...


Family Cable
Family AVR
CBL/SAT IN

Or...when distributing head end sourc s with a matrix switch.

Cable Box 1
DM IN 2

I have also started including electrician number wrap labels. So for example if you have 8 sources connected to 1-8 inputs on a DM switch I would put a 1-8 label depending on where it's connected. This saves me a lot of time when I have to swap out a dead or defective component. I do the same with a patch panel or surge protector. I can unplug it all and not need schematics or spreadsheet to wire things back up. Just connect 1-1 and 2-2.
